Abstract
Radiative efficiencies are reported for 10, 15, 20 and 25 kW, Phi = 0. 6 and 0.8, natural gas/air flames burned with an industrial fuel/air n ozzle and confined in a quartz radiant heating tube. The radiativee ef ficiencies of corresponding unconfined flames are also reported. Radia tive efficiencies of the confined flame/tube combination are at least three times higher than those of the unconfined flames suggesting stro ng participation by the confining quartz tube in the heat transfer pro cess.
